AWNING-ARM.'

' Application filed June '19,

. strength,-those parts that, are subjected to the most strain havinggreater strength and all side motion and wobbling of the arms be ingeliminated. Furthermore, my saidarm will, without the use of springs orthe like, always normally retain the awning in extended position, theparts of'the arm being so correlated and arranged as to cause the weightof the entire arm to exert its pressure on the outer end of the awningand all movement of the outer end of the awning caused by wind orotherwise, will be at once communicated to and taken up by the entirearm.

My invention furthermore embodies certain features of construction,arrangement and combinations of parts which are herein-- after morefully set forth and illustrated in the drawings, and will bemore'particularly pointed out in the appended claims. r

In the accompanyingdrawings in whlch similar reference charactersdesignate corresponding parts throughout the several views:

Figure 1 is a side elevation of an awning arm or support embodyingmyinvention;

Fig. 2 is a front elevation of the device illustrated in Fig. 1;

Fig. 3 is a plan view of the awning arm shown in Fig. l in itsextendedposition, the

outer member being broken away, and the securing bracket being shown insection.

Referring now to these drawings, 1 indicates the wall of a building, and3 the canvas of an awning which it is desired to support and guide andwhich, as illustrated, is adapted to be rolled up on a'roller 3". The

opposite ends of the roller, as shown, are

suitably mounted in bearings 3* on brackets suitably disposed andsecured to the wall 1, only one of which brackets is shown anddesignated 2. Each bracket 2 has, as illustrated, two pairs 4 and 5respectively of 1917. Serial no. 175,570.

' pivot bearings. e Pivoted in the bearings-dis an outwardly anddownwardly inclining base-member 6, comprising, ias shown,' par-'- allelspaced twin bars -6 6". To the respective twin members oftlr isbase-member Specification of Letters latent. Aug9 1 19 6 are pivoted at.their'ends two (substantially parallel intermediate members 7 and 8-re- 1 spectively, which members also, as illustrated, comprise.pazrallel twin :bars 7 and 8+l8 respectively, and to :the outer ends ofboth'of these members an outer member 9.

' Itwill be apparent that the connection of the intermediatemembers7jand 8 at theiropposlteends with the base member 6 and" outer member 9provides a parallel disposition of the base and outer members, aswell 7and-8 is pivoted i as a parallel disposition 'of the intermediatemembers, and this arrangement may be'said to form an -art1cularparallelogram. Suitable means for supporting and guiding the saidarticular parallelogram inte'rmediate its ends is provided which, asshown, comprises a' member plvoted at its inner end in the bearings 5,and at its outer end tothe, 7 twin 7 bars 8 --'8 intermediate the, endsthereof. v In order to limit the outward extension of the articular,parallelogram,- I' provide an extension 6 of the base-member, which atasuitable outward limit abuts against;

the twin bars 8 '8 of the arm 8.

It will be obvious from the above, that the tendency of the awningarmswill be to extend outwardly andjthat the entire weight of theseveral members of the said arms will be caused to press against theouter endof the awning, so that the'outer edge of the awning will beprevented'from flapping, without the use of springs or the like, andthat the slightest movement of the outer edge of the awning will immediately be communicated to all of themem bers of the arm. Furthermore,it will be obvious that an extremely simple, strong" 1 and rigidconstruction will be provided by i the arrangement hereinabovedescribed.

Having described my invention, I claim; 'f

1. An awning support comprising a pair of awning arms at opposite sidesof the awning, each side having a base member pivoted at a fixed pointtothe window frame, two parallel intermediate. members pivotally connectedto said base membercontiguous to the outer end thereof, an outer memberconnected at one end tothe awning site ends with the inner of said twoparallel members and a connection intermediate its ends with the otherof said two parallel members, a supporting member pivoted to one of saidintermediate members at one end and to a fixed point on the window frameat the opposite end and means for limiting the extension movement ofsaid members. i 1 V 1' '2.
